link is provided in neutral path of ac supply because it should provide a path for unbalanced currents , if we use fuse ,fuse may blow of and damage the entire system and also unbalanced currents may be more than the fuse rating

∙ 12y agoFuses (or circuit breakers) must always be inserted into the line conductor, never into the neutral conductor. So, if you need to isolate the circuit from the supply, you must disconnect both the line and the neutral conductors -this is achieved by removing the fuse from the line conductor, and opening the link in the neutral conductor.

Can you apply Norton Theorem to ac circuit?
yes
Why SCR does not latch in AC circuit?
because it doesnt
What is the significance of using inductor in ac circuit?
Current filtering
What is the purpose of the neutral conductor?
The purpose of neutral conductor is to carry the unbalanced load current. It is also a grounded conductor, which effectively places a limit on how much voltage could be present from hot to ground, a safety concern.
Can you apply the superposition theorem to ac circuit?
of course you can
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
What is an ac reactor?
A reactor in an AC circuit is basically an inductor which will filter spikes in source voltage. See the related link.
How can one circuit of a 4 four circuit service panel be providing 136v AC and the others 106volts when the incoming power is 240volts from the meter?
The neutral wire is open, or has a bad connection.
How can the flow of electrons in an electrical circuit change without the neutral becoming hot ex. AC Power?
The neutral conductor is bonded to ground, and is therefore always at earth potential, which is the zero-reference for voltage.
What is A ground-fault circuit interrupter?
== == If the current in an ac power circuit is not balanced between hot and neutral, possibly meaning some of the current is going through a human being to ground, a GFCI breaker or receptacle will break the circuit to keep the person from being electrocuted.
Why should current be reversed in an AC circuit?
The current in any AC circuit reverses every cycle.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
Why would four core armoured cable be used in a single phase circuit?
Four core armoured cable would be used in a circuit carrying 240 Volts 60 Hz AC that is installed in a location where it could get damaged, such as underground or under water. The 4 cores in the armoured cable would be used as the following conductors for the 240 V 60 Hz circuit: * "Red" hot (120V above Neutral)* "Black" Hot (120V below Neutral)* "Neutral"* "Ground" to protect the circuit, connected to the main incoming supply panel which feeds the circuit.
Does a 220 volt ac contact get a positive and a negative?
A 220 vac circuit has 2 hot wires and a neutral. The neutral stays at 0 volts and the hot wires vary between positive and negative. When one is positive, the other is negative.
Can you use an ac neutral on a coil powered by dc?
A neutral line can carry both AC and DC. Just make sure that the AC or DC is unable to pass through any components connected to the neutral line.
Can a red wire be neutral?
In ordinary circumstances, a red wire is a secondary hot wire in an AC circuit, or the positive power leg in a DC circuit. Red should not be used as a neutral. If it is used for something other than a hot wire it must be labeled on the wire at all connection points- and would STILL be a bad idea.
How do you tell a positive wire from negative wire with colors?
In a DC circuit Red is positive and Black is negative. In AC systems White is neutral and Ground is green or green-yellow stripe.
